Avantgarde Basshorn

angel · 19th March 2004, 10:42 PM

Does anyone know the technology behind the patent used for the Avantgarde basshorn?

According to their homepage, it appears they are using rather powerful drivers, and one might assume them to be equalizing the response to compensate for the rolloff caused by the small mouth of the horn.

But reading further, I note that they claim to have applied for a patent called Active Dynamic Radiation Impedance Conversion. This peaks my interest, because if they truly have discovered a way to change the acoustic impedance seen by a driver, despite a too small horn, it would be mighty tempting to DIY this with a Hornflex-style cabinet and a JBL 2226 driver.

probably its EQ or something.

Theres never a magic answer anyway...

the 2226 works for a large midbass horn if u want that...

Small horn? I've seen (and heard) this and they are anything but small.

You'll find its "compensation" not "conversion".

Active bass boost in other words.

Applying for a patent always makes it sound special.

you can apply for a patent for any stupid crap thesedays.....

Yeah, I know you can apply for (and someplaces get) a patent on anything nowadays, like the guy who recently patented the wheel.

They do list insane amounts of amplifier power, so I guess it's probably just equalization.

They might have just analyzed "average" program material, to determine the power distribution vs frequency, and decided on a lower corner for the horn that yields a boost over such a frequency range that you just don't run into the power limits under normal use, despite equalization.

you CAN make a basshorn tiny, like 25hz one,it just has lots of FR wobble :-)
in a normal room will you know :-D
